You are given the system of equations

If you want simply to know whether (1,1) is a solution of this system, then substitute x=1 and y=1 into both equations:

This means that (1,1) is a solution, because both iqualities hold.
the answer is d (i think) because anything aboveboard .90, whether it is positive or negative
32 cm, 21 cm, 24 cm, 33cm, 18cm, 30 cm
X² - 3x - 4 = 0
Reverse FOIL method . . .
(x - 4)(x + 1) = 0
one of the paranthesis has to be equal to zero if the other is not . . .
x - 4 = 0
<u><em>x = 4</em></u>
x + 1 = 0
<u><em>x = -1</em></u>
Answer:
15
Step-by-step explanation:
The answer is 15 because you have to solve the equation which gets you 15
first cancel out the x
Then you will get ur answer
